Predicting the September call-ups portion of the MLB season is an inexact science. Teams that are out of playoff contention may bring up top prospects to see how they will perform under major league pressure, while others may look at some minor leaguers who are putting up unexpectedly excellent numbers to see if they’re for real.

Teams in contention could call up top pitching prospects to serve in bullpen roles (the Rays did this in 2011 with Matt Moore) or add a young spark off the bench to shake a malaise and help ignite a late-season charge.

Joey Gallo played 25 games with the Rangers earlier this season and, despite getting off to a hot start, finished his run with a .218 average — hitting five home runs, stealing two bases and striking out 43 times.

Though his overall average in Triple-A looks ugly (.210), Gallo has been better lately, with a .289 average and five home runs over his past 10 games.

Gallo should be back up with the Rangers in the next few weeks, though his current team, Round Rock, looks like they will make a playoff run, which could complicate things a little bit. Still, if Gallo manages to play the entire month of September, we could see a .230 average with upwards of seven home runs and maybe a couple steals.

Rockies prospect Trevor Story should get a call-up when the rosters expand Sept. 1. He can play second, third or shortstop, and has a .277 average with 18 home runs and 17 steals at Double-A and Triple-A combined this season. It doesn’t appear as if Story has a position to play, but the Rockies could shift some infielders around to accommodate the 22-year-old, who could hit about .255-.265 with a few home runs and steals if he plays 20 September games.

The Twins’ Jose Berrios and the Cubs’ C.J. Edwards could be 2017 All-Stars and are tremendous names to stash away for keeper leagues. Berrios could be in the majors as early as this weekend, replacing an injured Tommy Milone in the Minnesota rotation. He has a 3.06 ERA and 1.11 WHIP over 22 starts this season, and has struck out a batter per inning. He is worth adding immediately in all formats.

Edwards, in an effort to limit strain on his shoulder, has spent all year in the bullpen (2.75 ERA, 1.22 WHIP, 72 strikeouts in 52 ¹/₃ innings) and could provide a spark in September, but will, barring some sort of insane twist of events, likely join the team as a member of the bullpen. He is a great keeper league add.

My favorite possible September call-up is Royals prospect Balbino Fuenmayor. The 25-year-old spent seven years in the Blue Jays organization before landing in the Independent leagues for half of 2013 and all of 2014. This season, he has been hammering the ball for the Royals across two levels, hitting .358 with 17 home runs and a .972 OPS. Baseball America’s 2014 Independent League Player of the Year, Fuenmayor was the oldest player at this year’s Futures Game and already has been signed to a 2016 minor league deal by the Royals.

There is really nowhere for Fuenmayor to play in Kansas City. But the Royals have a commanding lead in the AL Central, are four games up in the wild card, and probably will want to rest Kendrys Morales and Eric Hosmer down the stretch. Fuenmayor may end up being more of a daily fantasy baseball play, but he is worth keeping an eye on for the occasional home run when he gets a start.
